    I don't mind discussing this with you; I just didn't see where you
    were going with your questions. Care to rephrase?

    It all depends on how close you look. From a distance people are
    roughly Bayesian in many ways. But if you look real close at
    particular decisions you can certainly see a lot of error, and
    sometimes you can also see systematic deviations. So how big
    a deviation is "big"?
